The 'What The Hell' singer split from the Sum 41 star in 2010 after four years of marriage and despite their break-up, Avril insists the pair will always be very close.
She said: 'We're very good friends. He's family to me. We both respect and care for each other very much. We're in a great place.'
Avril and Deryck worked with each other on her new album 'Goodbye Lullaby' and as well as being good friends, she still has a lot of respect for his work.
She told The Sunday Times Magazine: ' have a lot of respect for him as an artist. He's one of the most talented people I know. He did an awesome job on my album.'
As well as having a close relationship with her ex, Avril ' who is now dating reality TV star Brody Jenner ' feels a connection with her fans.
The 26-year-old star said: ' have saved every single fan letter I've ever had mailed to me. When I talk to fans at after-shows or at meet-and-greets, I've had them cry and say how much my songs meant to them, and how it helps them in a hard time.'
